Idling Problems - engine fluttering and stalling

[JasonV]

Hey Guys,

Could use some advice.

I have a 1967 C10 with a V8 - 283. When driving, the engine seems to randomly cut-out and hesitate. When idling, randomly, the RPM's fall and it stalls. Start it back up...might idle for 2 minutes or 20 seconds, then dies again...randomly. On occasion, the RPM's just flutter downward, but they go up again, and it does not die.

This is what I have checked:

Cleaned the Spark Plugs
Cleaned Carburetor (2 barrel Rochester is new)
Checked Fuel Pump...it is pumping great.
Fuel Filter is new

Any advice on what else to check.

Thank you in advance for any advice.
